I have found that the pollution in our city is more and more serious. So we should think highly of the environment. But what on earth can we do? It must be a hard problem and we have a long way to go.
In my opinion, it s a good idea to sort the rubbish and send them to different factories. Why don t you treat the waste water, or it will be bad for our health. And how about treating and reusing newspaper and glass? Some harmful rubbish should be sent to a certain place and buried. Waste water will also be treated before it is poured into rivers. Maybe using environmental bags when you go shopping is also a good way to protect the environment . By the way,planting trees can be a great idea. Besides, there are many other ways.
Nowadays, protecting the environment is one of the most important things of the world. What s more, people has their own duty to protect and fight against the pollution. So we shouldn t be selfish. If everyone tries his best to do it, our earth will become better and better. At last, I am glad you will accept my advice.
